dreams of little houses

A couple nights ago, i had a dream that i was in a friends house. She had just moved there not that long ago, and we were exploring her house. We found out that there was a hidden part of the house upstairs. as we were walking around upstairs, everything just got smaller i guess. And we could explore anymore because we were too big for everything. All the furniture and everything was miniture, like a doll house.

I don't know what this means, but here is another example of smaller....things.

Almost everytime before i have a lucid dream, i'm in a house and somewhere in the back of my mind i know i'm dreaming, but in order for me to control the dream, i have to find my way outside of the house. The first time i had this dream i was trying to find my way outside, but i got distracted by this really little door. And i forgot all about the outside, and all i wanted to know was what was on the outside of this little door.

Does this mean anything? or do i have some kind of fascination with minature surroundings.
